Chimney Leaking Smoke Into Attic

Rerendering may stop the smoke but my advice would be to fit a twin wall stainless steel liner.

Chimney leaking smoke into attic.

Often ponding water will rust a hole in the simple flashing found on most chimneys. Another event that could happen although i have never heard of it actually happening is that you could get so much moisture in your attic that it could condense and roll down the stringer onto your chimney. This may make the smell of smoke more apparent in upstairs rooms as it leaks out of its ow2n flue and into other unused flues. Code requires a chimney have a cricket if it is thirty inches or wider.

If you ever had a chimney fire i wouldnt rely on the render stopping further damage. Have a certified chimney sweep inspect the chimney and make recommendations. If you see water entry in the attic on the uphill side of the chimney we know a chimney cricket is needed so water is not ponding in this area. Don t let one observation at a chimney distract you or convince you that further up close inspection is not needed.

If you have no smoke coming into your attic or other fireplace you ve confirmed. There is tremendous heat from chimney fires i have seen stacks split from the heat so for peace of mind get a liner in preferably by a hetas registered installer. It s hard to see them but the chimney needs to be free of any downdrafts. The other thing to check is downdrafts.

If the top of the chimmney is below the roof line downdrafts could be swirling down toward the chimney. Chimney leaks caused by condensation happen when a chimney is converted from wood burning to gas burning and isn t fitted with the proper liner. Smoke a little like water can end up in places where you would not expect. Solving chimney leaks can be difficult as there are many potential spots that could cause the leak.

Leaks may come from the chimney crown through the flue opening cap through the brick and the flashing is always a potential leak. Gas fireplaces give off fumes with moisture due to the lower temperatures and of the correct liner isn t installed that moisture can build up and seep through your chimney walls. Water leaking into a chimney increases the chance of damage to the chimney flue or chimney structure. Start a small test fire and this time open a window in the same room as the fireplace with the restored chimney.

It has happened and usually isn t discovered until people have spent a terrible sum fixing everything else.
